summary
Claims a production DR that brings up a secondary Azure region, provisions a Kubernetes cluster and restores database and messaging within two hours to meet a 6‑hour RTO while keeping always‑on spend to about $100/month. Standby firewall, application gateway and AKS remain powered down until automated pipelines restore them. Uses AKS, Terraform + Ansible and pipeline‑as‑code with image agents prewarmed in both regions. Postgres uses geo‑redundant backups, storage account failover is manual, and a front door DNS switch routes traffic to the recovered region.
